-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 - ------------------------------------------------------------------------- Debian Security Advisory DSA-4115-1 security@xxxxxxxxxx https://www.debian.org/security/ Salvatore Bonaccorso February 15, 2018 https://www.debian.org/security/faq - ------------------------------------------------------------------------- Package : quagga CVE ID : CVE-2018-5378 CVE-2018-5379 CVE-2018-5380 CVE-2018-5381 Several vulnerabilities have been discovered in Quagga, a routing daemon. The Common Vulnerabilities and Exposures project identifies the following issues: CVE-2018-5378 It was discovered that the Quagga BGP daemon, bgpd, does not properly bounds check data sent with a NOTIFY to a peer, if an attribute length is invalid. A configured BGP peer can take advantage of this bug to read memory from the bgpd process or cause a denial of service (daemon crash). https://www.quagga.net/security/Quagga-2018-0543.txt CVE-2018-5379 It was discovered that the Quagga BGP daemon, bgpd, can double-free memory when processing certain forms of UPDATE message, containing cluster-list and/or unknown attributes, resulting in a denial of service (bgpd daemon crash). https://www.quagga.net/security/Quagga-2018-1114.txt CVE-2018-5380 It was discovered that the Quagga BGP daemon, bgpd, does not properly handle internal BGP code-to-string conversion tables. https://www.quagga.net/security/Quagga-2018-1550.txt CVE-2018-5381 It was discovered that the Quagga BGP daemon, bgpd, can enter an infinite loop if sent an invalid OPEN message by a configured peer. A configured peer can take advantage of this flaw to cause a denial of service (bgpd daemon not responding to any other events; BGP sessions will drop and not be reestablished; unresponsive CLI interface). https://www.quagga.net/security/Quagga-2018-1975.txt For the oldstable distribution (jessie), these problems have been fixed in version 0.99.23.1-1+deb8u5. For the stable distribution (stretch), these problems have been fixed in version 1.1.1-3+deb9u2. We recommend that you upgrade your quagga packages.
